N14B16C / N18B16C
The N14 and N18B16C were co developed with PSA group and are essentially the same engine you’d find in the 207GTI, RCZ, DS3 etc. Branded as the EP6 or Prince engine by PSA. There are lots of variants of this engine. Even NA version but for our tuning packages we’ve focussed on the turbo charged variants fitted to the Mini. The N14 and N18 are different engines with the N18 featuring Valvetronic however from a tuning standpoint they respond in a very similar manner. While this engine gets a rough press for being a bit unreliable in our experience with proper tuning and maintenance these engines can actually be reliable and powerful even in a Motorsport environment. The B16C variant of these engines features slightly improved internals for higher performance and a lower compression ratio of 10.0:1 as opposed to 10.5:1.

300-330BHP - 400NM
Our HT330 tuning package for the N14 and N18 engines is the ultimate and the limit of what is currently possible on a stock frame turbo. There are 2 options for turbos in this tuning package which do give slightly different results.
Option 1: TTE300
This option generally yields around 300bhp on a healthy engine and good supporting modifications. This is by far the cheaper option.
Option 2: 308 GTI/RCZ R Borg Warner Turbo and Manifold
This option is a great option for anybody serious about performance from these engines. The manifold and turbo are lifted from the 270BHP variant of the EP6 engine and are a far improved design when compared to the turbo setup on the other N14/N18 or EP6 engines. Fitment is tight and there are modifications needed to the car which mean this kit is only really suitable for track or race cars. 330BHP and 400NM is achievable reliably and this has been tested in endurance race events.
Requirements:
Hybrid Tune Forged N14/N18 Engine
